The Liars have a plan: That's a whole lota drama, but don't worry, the Liars have a plan to gather as much info as possible while the party goes down. The press release explains that Emily (Shay Mitchell) will be “getting an insider’s view working the party,” Aria (Lucy Hale) will also be “working the crowd as a party-goer,” and Spencer (Troian Bellisario) will be “staked out at the hospital,” presumably to try to catch Garrett.Hanna's heartbreak: Meanwhile, the press release says poor Hanna (Ashley Benson) is "wallowing in heartbreak" after her split with Caleb (Tyler Blackburn). The silver lining, however, is that her sorrow "leads her to a shocking discovery." New characters: We'll meet two new characters this week, a boho chic photographer named Linda who takes on one of the Liars as her assistant (maybe Aria, since she took a photo class over the summer), and Ted, “a friendly church-rummage-sale coordinator.”Returning characters: In this episode, Paige (Lindsey Shaw) is back. Ezra (Ian Harding) will also definitely make an appearance after his notable absence in Episode 4 (and we'll be treated to a funny line about him from Spencer). We won't, however, see any Mona (Janel Parrish) this week.For more on the episode, check out all of the sneak peeks here.
